Clusterdata is just a wrapper function for "cluster" and "linkage", so it
requires patch #10009 (for "cluster").

Example included:

>> demo clusterdata
clusterdata example 1:
 X = [(randn (10, 2) * 0.25) + 1; (randn (20, 2) * 0.5) - 1];
 T = clusterdata (X, "linkage", "ward", "MaxClust", 2);
 scatter (X(:,1), X(:,2), 36, T, "filled");

Warning: this one requires a patch to linkage. 
The line:

if (nargin == 4) && (strcmp (savememory, "savememory"))

should indeed be:

if (nargin == 5) && (strcmp (savememory, "savememory"))

Because "savememory" must be followed by "on" or "off", so 5 parameters.
